- Abstract
- <jats:title>A<jats:sc>bstract</jats:sc> </jats:title><jats:p>We construct an effective field theory describing the decays of a heavy vector resonance <jats:italic>V</jats:italic> into Standard Model particles. The effective theory is built using an extension of Soft-Collinear Effective Theory called SCET<jats:sub>BSM</jats:sub>, which provides a rigorous framework for parameterizing decay matrix elements with manifest power counting in the ratio of the electroweak scale and the mass of the resonance, <jats:italic>λ</jats:italic><jats:italic>v/m</jats:italic><jats:sub><jats:italic>V</jats:italic></jats:sub>. Using the renormalization-group evolution of the couplings in the effective Lagrangian, large logarithms associated with this scale ratio can be resummed to all orders. We consider in detail the two-body decays of a heavy <jats:italic>Z′</jats:italic> boson and of a Kaluza-Klein gluon at leading and subleading order in <jats:italic>λ</jats:italic>. We illustrate the matching onto SCET<jats:sub>BSM</jats:sub> with a concrete example of a UV-complete new-physics model.</jats:p>
